Create an a Database Configuration:
 - database = Hypersonic SQL Db
 - driver = HSQL Db Memory
 - DatabaseName = AxonIvySystemDatabase
Open the SQL query window and execute:
 1.  `SCRIPT 'c:/temp/myHsqlDbExport.sql'` to export the full system db schema plus its content
 2. `DROP SCHEMA PUBLIC CASCADE` removes the default system db after a restart
 3. Paste the content of the previously exported SQL file to re-create the old version
Normally you will run into escaping and encoding problems in the last step. A practical solution could be that you only re-import the INSERT statements instead of the whole SCHEMA+DATA to avoid these problems.
